(+) 6 (15) 2 (25)
Anti-F3 (-) 9 (23) 1 (12)
(+) 30 (77) 7 (88)
Anti-F4 (-) 31 (80) 2 (25)
(+) 8 (20) 6 (75)a
Anti-F5 (-) 32 (82) 3 (38)
(+) 7 (18) 5 (62)b
Anti-F6 (-) 29 (74) 2 (25)
(+) 10 (26) 6 (75)c

(+) 20 (51) 4 (50)
  1. aP = 0.005, bP = 0.018, cP = 0.013 (Fisher's exact probability test). LRP2, low-density-lipoprotein-receptor-related protein 2.
